Who wrote 'Siyasatnama' (The Book of Government)?
Nizam-ul-Mulk Tusi wrote this Persian work on kingship and administration.
In the figure, lines $m$ and $k$ are parallel (m ∥ k), cut by a transversal. The angle on line $m$ is labeled $s°$ and the angle on line $k$ is labeled $t°$ (co-interior / same-side interior angles). If $s = t + 30$, what is the value of $t$?
Since $m \parallel k$, the angles $s°$ and $t°$ are co-interior (same-side interior) angles, which means they are supplementary:
$s + t = 180°$
We are also given: $s = t + 30$
Substituting: $(t + 30) + t = 180$
$2t + 30 = 180$
$2t = 150$
$t = 75°$
Which neurotransmitter is hydrolyzed by the enzyme monoamine oxidase (MAO)?
MAO breaks down monoamine neurotransmitters: dopamine, serotonin (5-HT), adrenaline, noradrenaline. Acetylcholine is broken down by acetylcholinesterase; glutamate is not a monoamine.
